Re: Structure of tel: URI

Also, note how phone-string is being defined in:

draft-allocchio-gstn-04.txt:

       phone-string = 1*( DTMF / pause / tonewait / written-sep )

       DTMF = ( DIGIT / "#" / "*" / "A" / "B" / "C" / "D" )

       written-sep = ( "-" / "." )

       pause = "p"

       tonewait = "w"

       gstn-phone = ( global-phone / local-phone )

       global-phone = "+" 1*( DIGIT / written-sep )

       local-phone =  [ exit-code ] dial-number

       local-phone =/ exit-code [ dial-number ]

       exit-code = phone-string

       dial-number = phone-string

       subaddr-string = phone-string

       post-dial = phone-string
